Add the capability to query information from a submit queue.
The first available parameter is for querying the number of GPU faults
(hangs) that can be attributed to the queue.
This is useful for implementing context robustness. A user context can

For throttling to work correctly, we always need a baseline vblank
count last_flip_vblank that increments at start of front-porch.
This is the case for drm_crtc_vblank_count() in non-VRR mode, where
the vblank irq fires at start of front-porch and triggers DRM core
vblank handling, but it is no
We want vblank counts and timestamps of flip completion as sent
in pageflip completion events to be consistent with the vblank
count and timestamp of the vblank of flip completion, like in non
VRR mode.
In VRR mode, drm_update_vblank_count() - and thereby vblank
count and timestamp updates - must

Patch 1/4 is still the same though. Don't know if i or Nicholas could
fix it in a followup patch, or this one needs more
During VRR mode we can not allow vblank irq dis-/enable
transitions, as an enable after a disable can happen at
an arbitrary time during the video refresh cycle, e.g.,
with a high likelyhood inside vblank front-porch. An
enable during front-porch would cause vblank timestamp
updates/calculations
